The U.S. seized a son-in-law of Osama bin Laden who once served as an al Qaeda spokesman and flew him to New York to face trial, an antiterrorism coup that casts light on the group’s murky relationship with Iran.

Sulaiman Abu Ghaith, who was captured in Jordan, has been talking to Federal Bureau of Investigation agents for several days in New York City, according to multiple people familiar with the case. He was captured after leaving Iran, which has sheltered remnants of the global terror group.

The Justice Department on Thursday unsealed an indictment charging Mr. Abu Ghaith with conspiring to kill Americans, and he is set to appear in federal court in Manhattan Friday morning. It was unclear Thursday if Mr. Abu Ghaith had a lawyer representing him.

The arrest has also reanimated the debate about whether terror suspects should be tried before civilian judges or military tribunals.

There is no official word yet on whether he is being waterboarded or forced to listen to John Kerry speeches as authorities try to extract information.

Also, Mr. President, can we stop pretending that Iran is ever going to play nice?
